Don't use an uninitialized pointer in wxCairoContext ctor from wxPrinterDC in
wxGTK if retrieving Cairo context of the DC failed, set m_context to NULL in
this case (not sure if this is still not going to crash when used in
cairo_translate() below though).
Initialize m_buffer to avoid crashes when deleting it in Cairo-based
wxGraphicsContext implementation for bitmaps created from the native ones.
Don't leave the bitmap size uninitialized neither, this might not result in
crashes, but is definitely wrong as well.

This merges in the latest sources from GSoC 2014 wxQt project with just a few
minor corrections, mostly undoing wrong changes to common files in that branch
(results of a previous bad merge?) and getting rid of whitespace-only changes.
Also remove debug logging from wxGrid.

Allow the code to determine which underlying technology is used for
implementing wxGraphics API. This is needed by the unit tests to account for
the known differences between platforms and may be useful in other cases.
Closes#16154.

It was assumed that all callers were going to unref the cairo_t, but that is not
true, so callers that are going to unref it should ref it themselves.

This keyword is not expanded by Git which means it's not replaced with the
correct revision value in the releases made using git-based scripts and it's
confusing to have lines with unexpanded "$Id$" in the released files. As
expanding them with Git is not that simple (it could be done with git archive
and export-subst attribute) and there are not many benefits in having them in
the first place, just remove all these lines.
If nothing else, this will make an eventual transition to Git simpler.
Closes#14487.

Remove unused Unload(), wxCairoCleanUp(), m_loaded and gCairoRenderer, and redundant Load()
and EnsureIsLoaded(). Just call wxCairoInit() directly, and for GTK do nothing at all.

Refactor the pen/brushes classes to introduce a common base class for them
containing their colour and hatch pattern and stipple bitmap, if any.
And actually create the hatched pattern and use it.

cairo_win32_surface_create() must be passed the window HDC and not HWND
itself, the old code calling it was broken.
Add WindowHDC object and pass its HDC to this function now to make it work.

This member was only used in wxGTK-specific code but it was declared for all
platforms which was unnecessary and confusing.
Move its declaration in wxGTK-only section of the class.

This is mostly important to allow using wxImage-based wxGraphicsContext
without requiring X server connection under Unix: as wxFont can't be used
without X server, we needed another way to create wxGraphicsFont in this case.

Provide a way to use wxGraphicsContext to draw on wxImage.
This is implemented internally by drawing on wxGraphicsBitmap which can be now
also created from wxImage.
Add a test of the new functionality to the image sample.

wxCairoContext class declared default ctor which wasn't implemented and even
couldn't be implemented because its base class didn't have any default ctor
neither.
Fix this by providing a ctor taking wxGraphicsRenderer* and implement it.

Extract the code for buffer and surface creation into separate helper
functions so that they could be reused by other constructors (to be added in
the next commits).
Also use cairo_format_stride_for_width(), if available, to compute the stride
for the surfaces we create instead of hard coding 4*width.
